Description

Technical Field

[0001] The utility model relates to the technical field of shearing machine equipment, in particular to a shearing machine with a protective structure. Background Art

[0002] During the processing and production of metal sheets, they need to go through various processes, including shearing. Shearing is to obtain metal sheets of fixed size, so as to facilitate subsequent shaping, drilling and other operations. When shearing metal sheets, you need to use a shearing machine. A shearing machine is a mechanical equipment used to shear metal sheets.

[0003] At present, when using a shearing machine to shear the plate, it is necessary to manually push the plate on the workbench to the shearing tool. During the movement of the plate, friction will occur with the workbench, which is easy to cause scratches on the plate surface and reduce the processing quality. At the same time, manual operation also increases safety hazards. Therefore, in response to the above problems, we proposed a new type of shearing machine with a protective structure. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a shearing machine with a protective structure, including a workbench 1 and a motor 3. A feed roller support 14 is embedded in the top of the workbench 1 near the front side, and slide grooves 11 are opened at the top of the workbench 1 near the left and right sides. A U-shaped frame 2 is slidably arranged between the two slide grooves 11, and a bracket 21 is symmetrically fixedly installed on the top of the U-shaped frame 2. An electric push rod 22 is fixedly installed on the bottom of the bracket 21. The telescopic end of the electric push rod 22 slides through the top of the bracket 21 and extends to the bottom. A threaded screw 31 is fixedly installed at the output end of the motor 3, and connecting plates 32 are rotatably arranged on the outer surface of the threaded screw 31 near the two ends. The connecting plate 32 is fixedly installed at the bottom of the workbench 1, and a threaded block 23 is threadedly arranged on the outer surface of the threaded screw 31 near the middle, and the top of the threaded block 23 is fixedly connected to the bottom of the U-shaped frame 2.

[0023] The effect achieved by the entire embodiment 1 is that the plate is placed on the top of the workbench 1, and the bottom of the plate can be supported by the feed roller support 14, and then the threaded screw 31 is driven to rotate by starting the motor 3, thereby driving the U-shaped frame 2 to move backward through the threaded block 23. The U-shaped frame 2 is composed of two parts, the upper half slides inside the slide groove 11, and the lower half is under the slide groove 11 and connected to the threaded block 23. The threaded screw 31 is supported by the setting of the connecting plate 32. When the top of the U-shaped frame 2 moves to the edge position of the plate, the end of the electric push rod 22 is started to move downward, so that the plate can be clamped and fixed. After the plate is completely fixed, the U-shaped frame 2 continues to move backward, which can push the plate to move backward synchronously. Since the bottom of the plate is supported by the feed roller support 14, the feed roller support 14 rolls due to friction when the plate moves, thereby avoiding direct contact between the workbench 1 and the plate to cause scratches, improving the processing quality, and at the same time, avoiding manual pushing of the plate, reducing safety hazards.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the bottom of the workbench 1 is fixedly installed with supporting legs 12 near the four corners, the top of the workbench 1 is embedded with a discharging roller support 15 near the rear side, the top of the workbench 1 is provided with a slot 13 between the chute 11 and the discharging roller support 15, the top of the workbench 1 is fixedly installed with a gantry 4 between the chute 11 and the discharging roller support 15, the top of the gantry 4 is fixedly installed with a hydraulic rod 41, the telescopic end of the hydraulic rod 41 slides through the top of the gantry 4 and extends to the bottom, and the telescopic end of the hydraulic rod 41 is fixedly installed with a mounting plate 42, a guide rod 43 is symmetrically fixedly installed on the top of the mounting plate 42, and the outer surface of the guide rod 43 slides through the inner top of the gantry 4 and extends to the top, a blade 44 is provided near the middle of the bottom of the mounting plate 42, and a plurality of springs 45 are symmetrically fixedly connected to the bottom of the mounting plate 42 near the edge, a pressure block 47 is fixedly connected to the bottom end of the spring 45, and a limit rod 46 is fixedly connected to the top end of the pressure block 47, and the limit rod 46 is sleeved inside the spring 45, and the outer surface of the limit rod 46 slides through the bottom of the mounting plate 42 and extends to the top.

[0025] The effect achieved by the entire embodiment 2 is that when the position of the plate to be sheared moves to below the blade 44, the mounting plate 42 is pushed downward by starting the hydraulic rod 41, so that the blade 44 descends, which plays a role in shearing the plate. When the mounting plate 42 moves downward, the guide rod 43 penetrates the gantry 4 and slides with each other, which guides and limits the mounting plate 42, thereby improving stability. When the blade 44 descends, the pressure block 47 will first contact the plate, and cooperate with the incomplete contraction of the spring 45 to fix the plate, thereby avoiding bending and rebounding of the plate during the cutting process, further reducing safety hazards. When the pressure block 47 moves downward, the limit rod 46 penetrates the mounting plate 42 and slides with each other, which guides and limits the pressure block 47, thereby improving stability. By setting the discharge roller support 15, it is convenient to move the plate out of the shearing area, which is convenient for the staff to take.

[0026] Working principle: When in use, place the plate on the top of the workbench 1, and the bottom of the plate can be supported by the feed roller support 14, and then the threaded screw 31 is driven to rotate by starting the motor 3, so that the U-shaped frame 2 is driven to move backward through the threaded block 23. When the top of the U-shaped frame 2 moves to the edge of the plate, the end of the electric push rod 22 is started to move downward, so that the plate can be clamped and fixed. After the plate is completely fixed, the U-shaped frame 2 continues to move backward, which can push the plate to move backward synchronously. Since the bottom of the plate is supported by the feed roller support 14, the feed roller support 14 rolls due to friction when the plate moves, thereby avoiding work The table and the plate are in direct contact to produce scratches, which improves the processing quality. At the same time, it avoids manually pushing the plate and reduces safety hazards. When the position of the plate to be sheared moves to below the blade 44, the blade 44 is lowered by starting the hydraulic rod 41, so that the plate can be sheared. When the blade 44 descends, the pressure block 47 will first contact the plate, and cooperate with the incomplete contraction of the spring 45 to fix the plate, avoiding bending and rebound of the plate during the cutting process, further reducing safety hazards. After the shearing is completed, the front plate is pushed to the cut plate onto the discharge roller support 15, thereby moving the plate out of the shearing area for the convenience of the staff to take it.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
